Airflow Direction; Timer Control - Panasonic CS-MRE7MKE Service Manual

13.5. Airflow Direction

1. There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by vertical vanes).
2. Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat exchanger
temperature and intake air temperature) and manual (angles of direction can be adjusted using remote control).

Operation Mode

Soft Dry
1. Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the angles as stated
above. For heating mode operation, the angle of the vane depands on the indoor heat exchanger temperature as Figure 1
below. It does not swing during fan motor stop. When the air conditioner is stopped using remote control, the vane will shift to
close position.
2. Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated above and the positions
of the vane are as Figure 2 below. When the air conditioner is stopped using remote control, the vane will shift to close
position.

13.6. Timer Control

13.6.1. ON Timer Control
• ON timer can be set using remote control, the unit with timer set will start operate earlier than the setting time. This is to provide
a comfortable environment when reaching the set ON time.
• 60 minutes before the set time, indoor (at fan speed of Lo-) and outdoor fan motor start operate for 30 seconds to determine the
indoor intake air temperature and outdoor air temperature in order to judge the operation starting time.
• From the above judgment, the decided operation will start operate earlier than the set time as shown below.
